Unable to assign floating licenses to users

Hello,

We have a floating license assignment issue for registered and active users in the admin interface.

Users receive the invitation email and are able to create their accounts on enscape.

When the user logs in to enscape from Skechup with the account registered in the admin interface, he does not receive a license.

If the user enters the license manually and is no longer active in the administration interface, enscape remains active with the manually entered license

How do I ensure that registered and active users in the admin interface receive a floating license when they log in with their accounts ?

Have a nice day.
